Since the broadest aspect ol the present invention is concerned with the provision olf a gravity lock by which the plug member is kept by its own weight and the weight of the appliance attached thereto in predetermined relation. to the supporting element it will be understood that the particular devices by which the plug member is engaged with the supporting element may be changed Without departing from the spirit of the, invention. That is to say, in so far as this phase is concerned the supporting plate L might be of different design but adapted lo receive elements on the plug member which are equivalent to the flanges g2 ior supporting engagement and a gravity locking relation be insured without providing the triangular' recess in the plate hereinbetore relerred to. By way of illustration, the gravity lock may be explained with reference to the drawings. The slots a2 in the peripheral walls a of the opening in the plate a.- are shouldered as at a, adjacent one end to providealoutments for 'co-operation with the flanges g2 of the plug carrier tf/ after the flanges have been moved along the slots n. until they clear the abutlneuts a. and drop in back of them. In use, for instance, the generally triangular plugelement is introduced into thecomplementary recess and the plug revolved to carry the flanges g2 into the respective slots a?. After the lianges have passed the respective abutments a. in the slots the plug is permitted to drop by gravity so that the flanges rest against the abutments a3' and are held against reverse rotation thereby. In order to overcome the action of gravity in insuring this locking relationship it is necesary to raise the plug elcment bodily against the pull of gravity until the flanges g2 are above the respective abutments a? when the plug may be revolved contrariwise to withdraw the flanges from the slots and permit the plug to be witlulrawn 'from the recess. positive retaining element to prevenl this disengagement o'l`: the plug with lhe supporting element nia v. lor safety" sake, be provided in the ilorni oil au annular nut which may be threaded onto the outer side oll the circular plug carrier y] after the parts have been brought in such relationship as lo bring about the gravity locking engagement.

The recess formed in he plate inalv'es die slots in ils peripheral walls invisible at ordinary angles of view. When the plug is not in use the resulting installation is neat. lllhcn the plug is introduced into (he recess and turned home `lor locking engagement with lhe supporting eleuieni the paris are iu compact relationship, (he plug being partly housed within the recess.

Changes in details ol' construction, espe cialljv7 as indicated herein, may be inade williout departing from the spirit ol lhe invention provided the results are secured.

that I claim is:

In an electrical receptacle, a ceiling plaie, a liange formed by a turned in porliou oi lhe plate and providing a recess resemblilig a polygon, openings in the llange in bach olthe ceiling plate, a plug adapted to be in serl'ed in the recess, a shell over the plug, means to secure the two while pcrlni'ling relative rotative movement between the. two, a polygonal vl'lange on the shell adapted lo lit into the recess and eng ging the openings` upon turning of the shell aller insertion into the recess, and shoulders on the lower edges of the openings over which the llanges` ride.

whereby the gravitational force on the shell prevents backward movement thereo't without lifting.
